Lets do some conservative math nowAdsense has 5 million users : $200 Million in unpaid revenuesAdsense has 1 million users: $40 Million unpaidAdsense has only 500000 users: $20 Million unpaidThese are still large enough numbers to make us want to question what is going on.

Thus, Google could potentially be holding about $400 Million in cash that they probably never will payout because 80% of its users (like me) will never get enough hits to make $100 any time in the near future. Is this a deliberate strategy? Wonder if Google's earnings statements reflect these numbers, but I'm too lazy to check that out!

The least Google should do is to at least payout interest income to these users in addition to what they have already earned.
